Cardiology Clinical Vignettes: A Practice Audit Reference
Clinical vignettes are usually treated as examination furniture, something to be endured in blocks of sixty before a sitting. Used differently, they are the cheapest audit tool available to a doctor in international practice: a way of testing whether the decisions you make on a Tuesday afternoon still match the evidence, and whether the habits your department has absorbed are defensible. A doctor preparing for a certifying or recertifying examination abroad is doing both things at once. The vignettes below are grouped by the decision archetype they test, because those archetypes recur far more often at the bedside than any individual fact does.

How to use vignettes as an audit
Work each case cold, commit to an answer in writing, then compare your reasoning rather than your answer with the explanation. Most wrong answers among experienced clinicians are not knowledge failures; they are the substitution of local habit for evidence, or the reading of a stem for the diagnosis rather than for the decision being asked about. Keep a one-line note of which of those two produced each error. After thirty cases the pattern will be obvious, and it is usually correctable in a fortnight.
The decision points
1. The reperfusion geography decision
A 52-year-old presents to a rural hospital ninety minutes after symptom onset with inferior ST elevation and a systolic pressure of 96 mmHg. The nearest interventional laboratory is a 150-minute transfer. The decision being tested is not diagnosis but timing: when anticipated delay to intervention exceeds the accepted window, fibrinolysis followed by transfer for angiography is the correct pathway, with rescue angiography if ST resolution fails at sixty to ninety minutes. The trap is the assumption that a patient destined for a catheterisation laboratory should wait for it. Right-sided leads belong in this stem too, since right ventricular involvement changes the fluid and nitrate decision immediately.
2. The antithrombotic combination decision
A 74-year-old with atrial fibrillation on an oral anticoagulant undergoes stenting for an acute coronary syndrome. What leaves the regimen, and when? The evidence assembled in AUGUSTUS and PIONEER AF-PCI points consistently in one direction: keep triple therapy brief, then continue the anticoagulant with a single antiplatelet agent, usually clopidogrel. Aspirin is the component that departs. Two errors recur in real practice as well as in question stems: reducing the anticoagulant to a dose never validated for stroke prevention, and retaining aspirin while stopping the P2Y12 inhibitor. The practical framework sits in our acute coronary syndromes reference.
3. The revascularisation strategy decision
Stable symptoms, multivessel disease, preserved ventricular function, and a patient who wants to know whether stenting will prevent a heart attack. ISCHEMIA reframed this conversation: in stable disease with preserved function, an initial invasive strategy improves symptoms without demonstrating a mortality advantage over optimal medical therapy, so the honest answer is about angina burden rather than survival. Where the left main or complex multivessel disease is involved, SYNTAX and EXCEL define the anatomical complexity conversation and the surgical comparison. Vignettes in this area reward candidates who separate symptomatic benefit from prognostic benefit, and so do patients.
4. The lipid escalation decision
A patient two years after infarction remains above target on a moderate statin dose, with normal transaminases and no myalgia. The decision is escalation, not substitution: maximise the tolerated statin, add ezetimibe, and consider proprotein convertase subtilisin kexin type 9 inhibition where targets remain unmet and access permits. The distractor is usually a switch to a different statin at equivalent potency, which changes nothing. Reported intolerance deserves rechallenge and a genuine assessment rather than acceptance, and our modern lipidology reference covers the sequence in detail.
5. The discordant echocardiogram decision
Calculated aortic valve area in the severe range, mean gradient below the severe threshold, ejection fraction 38 per cent. The decision is what to do next rather than what to call it: measure stroke volume index, and if flow is low, proceed to dobutamine stress echocardiography or calcium scoring rather than reporting moderate disease. The PARTNER programme extended intervention across the risk spectrum, which makes accurate severity assessment more consequential than it used to be, not less. Measurement discipline for these studies is set out in our practical echocardiography reference.
6. The heart failure therapy sequencing decision
Reduced ejection fraction, persisting symptoms, and a stem listing current medication. These vignettes test whether you start the disease-modifying agents together at low dose and titrate, rather than maximising one before introducing the next. They also test device eligibility: reassessment of ejection fraction after a period of optimised therapy before implantation, and consideration of resynchronisation where the QRS morphology and duration support it. Secondary mitral regurgitation persisting after optimisation is where COAPT enters the conversation, and the selection criteria matter more than the headline result. Wider management sequencing is covered across the heart failure, rhythm and risk hub.
7. The rhythm risk decision
Syncope, a structurally normal heart on echocardiography, and a resting tracing with a subtle right precordial abnormality. The decision tested is disposition: which patient with syncope can be discharged and which requires monitoring and specialist assessment. Exertional syncope, syncope without prodrome, a family history of sudden death, and any abnormal resting tracing all move the patient into the investigate-before-discharge group. Pattern recognition for the inherited syndromes is the part most experienced clinicians have let decay, and it is disproportionately represented in both examinations and coroners’ reports.
When to escalate, transfer or call for help
- Immediately: failed reperfusion after fibrinolysis, shock complicating infarction, or sustained ventricular arrhythmia with structural disease. These are the real-world versions of the stems above and they do not wait for the morning round.
- Within days: discordant valve assessment, newly reduced ventricular function without an explanation, or syncope with an abnormal tracing. Each needs a second modality or a specialist opinion rather than a clinic review in three months.
- Before you change a regimen: any combination of anticoagulation and recent stenting. This is the single commonest area in which confident but incorrect decisions are made by clinicians working without cardiology support.
- For your own calibration: discuss disagreements with a colleague who trained in a different system. Structured case discussion of this kind is what the landmark cardiology case collection and the examination preparation hub are designed to provoke.
What to document
- For each practice case: your answer before checking, the correct answer, and whether the error was knowledge, misreading or habit.
- Domain-level accuracy over time, rather than an overall percentage that conceals the weak areas.
- In real practice, the reasoning behind any decision that departs from the local norm, with the evidence named.
- The trial or guideline you relied on when the decision was contested, so that the record defends itself later.
- Any decision deferred pending a second opinion, with the date the opinion was requested.
Bench card
| Archetype | The discriminator | Evidence anchor |
|---|---|---|
| Reperfusion geography | Anticipated transfer delay, not preference | Fibrinolysis then routine early angiography |
| Anticoagulant plus stent | Which agent leaves, and when | AUGUSTUS, PIONEER AF-PCI |
| Stable multivessel disease | Symptom benefit versus prognostic benefit | ISCHEMIA, SYNTAX, EXCEL |
| Residual lipid risk | Escalate, do not substitute | Statin plus ezetimibe, then further escalation |
| Discordant valve grading | Stroke volume index | PARTNER-era severity assessment |
| Reduced ejection fraction | Combination initiation, then reassessment | Device eligibility after optimisation; COAPT for selected mitral regurgitation |
| Syncope disposition | Exertional, unheralded, or abnormal tracing | Investigate before discharge |
Volume matters, but only with a written error log attached. Question sets structured by domain are available in mastery of cardiology multiple choice questions and the cardiology self-assessment question bank. The original high-yield revision version of this material is published as this set of high-yield cardiology examination questions.
Questions from the floor
How many practice cases are actually necessary?
Fewer than most candidates assume, provided each is worked properly. Two thousand cases skimmed for the answer teach less than six hundred worked cold with a maintained error log. If you are not writing down why you were wrong, additional volume is largely wasted effort.
Are questions written against another country’s guidelines still useful?
Yes, and the divergences are instructive in themselves. Where two traditions differ on a threshold, that difference is usually where the evidence is genuinely uncertain, which is worth knowing at the bedside as much as in an examination hall.
Should experienced consultants practise cases at all, or just read?
Practise. Experience produces fluent but sometimes outdated reasoning, and vignettes are the fastest way to detect where practice has drifted from evidence. Many senior clinicians find their weakest domains are the ones they feel most confident about.
What is the best use of the final fortnight?
Re-work previously failed cases and rehearse image and tracing interpretation against the clock. New material at that stage displaces consolidated knowledge and raises anxiety without raising scores. Rehearsing the archetypes in the bench card above, rather than reading new chapters, is the highest-value use of those final days.
